Researcher Puts Cows In A Bubble To Measure Emissions

Davis, CA — Researchers are trying to answer a question plaguing one of California´s largest agricultural industries; how much gas does a cow emit?

The findings will be used to write the state´s first air quality regulations for dairies and could affect regulations nationwide.

There are more than 3 million cows in California, the vast majority living in the booming Central Valley.

On August 1st, the San Joaquin Valley Air Pollution Control District will announce its new emissions factor for cows; a figure that will eventually determine which dairies must apply for air quality permits and invest in mitigating air pollution equipment.
